1 3-GL, 4-GL, 5-GL and 5A-GL knee mills with gearless drive heads turret mills for the new millennium 5-GL Travels 32 x 16 to 40 x /2 Hp or 7 1/2 Hp heads 12 x 50 or 13 x 59 tables R-8, # 30 or # 40 taper spindles Square or dovetail ways 5A-GL

2 The VF series: for those who appreciate the best! The 5-GL-VF This model is prepared with a 3 axis Fagor digital readout. The 3rd axis can be on the quill or the knee RPM gearless head - up to 7 1/2 Hp spindle drive pentant with speed display, joysticks for feeds, coolant control etc 225 IPM rapid traverse on X and Y feeds 1/2 to 100 IPM on X and Y rapid traverse for knee positioning CNC grade ballscrews on X and Y advanced digital readout is standard, and diplays feed rate, makes bolt hole patterns pockets etc. The 3-GL-VF Pictured here with the Fagor readout, is also available with the Heidenhain ND-710 readout shown on the back inside cover on a bed mill. CNC type servo motors and amplifiers make CNC upgrade in the future very easy

10 The heart of our GL knee mills is our vector drive heads. With about 85 less parts than a Bridgeport vari-disc type head, maintenance is reduced to near zero. Only 3 moving parts in the drive train. The motor shaft and pulley, the drive belt, and the spindle and pulley. Gone are vari-disks, springs, brake pads and fingers, hi-lo clutch and shift mechanism, back gears and the extra timing belt, speed adjusting handwheel with its inaccurate setting, chain linkage etc. What you get is a state of the art electronic drive that is equally happy to run on 230/3/60 or 220/1/60. Accurate speed settings. Spindle speeds to 6,000 rpm. Increased power output to 4 1/2 Hp on R-8 class heads and 7 1/2 Hp on the heavier 5 series heads. It can t get much simpler than this. - motor shaft and pulley - belt - spindle hub and spindle That s about 85 fewer parts than a typical vari-disk type head. It s so reliable that we guarantee the spindle drive mechanism for 3 years. A Note about the Castings Almost every milling machine from Taiwan has the big M cast in frame. indicating that the main castings are Meehanite. There are dozens of grades of Meehanite. Our frames are GA-50 and 350, some of the best formulations for machine tools. Some other builders use lower, less expensive grades. Machine tool service people who drill castings to install digital readouts will tell you that some drill like butter and some are like drilling steel. At the time of preparation of this catalog we have a 5-VK mill that was built in 1994 and fitted with a CNC system. The box ways on the cross slide can easily be checked with a micrometer for wear. They are still within 1/10th of a thou, front > middle > back - after 7 years of CNC use as the only mill in the shop! We challenge you to find out the certified castings used on any other machine you are considering, then check to get the real story. There you will see that come grades have less than half the tensile strenght and resistance to elasticity than the grade we use. Better castings and Turcite are worth the investment!!!

11 If you want larger capacity or more stability... we have bed mills available with travels 32 x 20 x 20 to 50 x 22 x 20 and capacity under the spindle of up to 30. Quill type, medium duty and heavy duty machining center type heads are available. The TW-50-RH with servo feeds on all 3 axes, 15 Hp spindle drive and 2,000 lb table load. Our current location, 5 minutes from the Toronto International Airport Our Background HH Roberts Machinery was founded in Toronto in the early 1930 s and now has the 3rd and 4th generations of the family active. We have grown from a used machinery dealer / repair and rebuild shop to one of the major machine tool distributors in Canada. We have a modern 20,000 square foot facility just minutes from the Toronto International Airport. We have been offering mills prepared by Topwell Machines, Taiwan for 20 years, and we have been fitting them with Anilam CNCs for more than 10 years. There are over 30 models to choose from, including knee Our founder Harold Hobday Roberts, in front of our first shop,circa mills, bed mills, open and enclosed machining centers, our unique HV combination horizontal / vertical machining center and bridge type graphite mills not detailed in this catalog. We keep nearly 100 machine frames in stock, ready to be assembled on your order. We have a complete stock of spare parts available at very reasonable costs for overnight shipping. The dealers we sell through in the USA have demonstrated a commitment to the Anilam system and should be capable of supporting your staff and the machine in startup, training and after sales service.
